[kepler-dev] getting links from a compositeEntity

I've got the relation objects, but what I'm trying to get at is the 
<link> moml elements.  When I call exportMoML() on a ComponentRelation, 
I get something like this:
<relation name="relation" class="ptolemy.actor.TypedIORelation">

I want that but also the <link> elements that tell what the relation is 
linked to.  Do I have to go through the port list to get these?  How do 
I get the links to serialize.
